Guided Self-help for Binge Eating

March 31, 2017 updated by: Oxford Health NHS Foundation Trust

Guided self-help (GSH) is a recommended first-step treatment for bulimia nervosa, binge eating disorder, and atypical variants of these disorders. The current study proposes to investigate the effectiveness of providing GSH either face-to-face or via e-mail, also using a delayed treatment control condition. Symptom outcomes will be assessed, and an estimate of cost-effectiveness made. Results are proposed to be disseminated locally and internationally (through submission to conferences and peer-reviewed journals), and will hopefully inform local service provision.

Please note that we are only able to offer the intervention to individuals who are currently registered with a General Practitioner that is covered by Oxford Health NHS Foundation Trust - this is typically restricted to practices in Oxfordshire, Buckinghamshire, and parts of Wiltshire.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: Self-help
In this condition, participants complete a self-help intervention with the support of a therapist. This lasts 12 weeks.

Participants in this arm will receive face-to-face self-help; that is, self-help with the support of a therapist, attending the clinic in person.
Other: E-mail self-help
Participants in this arm will receive e-mail self-help; that is, self-help with the support of a therapist, provided via e-mail.
Other: Waiting List
One third of participants will be allocated to a treatment waiting list, after which they will be randomised to one of the other two arms.
Other: Waiting List
Waiting list condition - participants assigned to a waiting list (no intervention) condition

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
EDE-Q
Time Frame: Change in symptoms between Assessment, Start-of-treatment (approx. 3 months later), End-of-treatment (approx. 12 weeks after start of treatment), and 6-month follow-up
The EDE-Q is given as a measure of eating disorder symptoms in a standardised pack of measures, all given at Assessment, Start-of-treatment, End-of-treatment, and 6-month follow-up. "Assessment" concerns the patient's first contact with the Eating Disorders Service. Start-of-treatment will proceed as soon as possible; at present, the waiting list is around 3 months. Treatment lasts 12 weeks, so End-of-treatment measures will be given approximately 12 weeks after start of treatment. There is a 6-month follow-up. Binge eating is the primary outcome measure, with other eating disorder symptoms as secondary measures. Change in these symptoms will be assessed over the course of treatment.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame
CORE-OM
Time Frame: Change in symptoms between Assessment, Start-of-treatment (approx. 3 months later), End-of-treatment (approx. 12 weeks after start of treatment), and 6-month follow-up

"Assessment" concerns the patient's first contact with the Eating Disorders Service. Start-of-treatment will proceed as soon as possible; at present, the waiting list is around 3 months. Treatment lasts 12 weeks, so End-of-treatment measures will be given approximately 12 weeks after start of treatment. There is a 6-month follow-up.

The RSES is given as a measure of self-esteem in a standardised pack of measures, all given at Assessment, Start-of-treatment, End-of-treatment, and 6-month follow-up. "Assessment" concerns the patient's first contact with the Eating Disorders Service. Start-of-treatment will proceed as soon as possible; at present, the waiting list is around 3 months. Treatment lasts 12 weeks, so End-of-treatment measures will be given approximately 12 weeks after start of treatment. There is a 6-month follow-up.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Therapist Time
Time Frame: After every contact with the patient (approx. weekly), including weekly sessions during treatment (12 weeks)
Therapists are asked to indicate (to the nearest 5 minutes) how much time they spend doing clinical / administrative tasks for each patient (patient name not included). Although there are no formal guidelines for how therapists report their time, it should accurately record all contact with patients, and thus is suggested to be completed approximately weekly.
